I am curious because I am getting a physical at my local health center and getting everything checked including test and IGF. For someone who is 22 years old what would be a baseline or normal IGF I should expect in ng/ml? Also if you take gh, the only real test that works every time is the IGF test and I am curious what a generic blue top from china would result in and pharm grade US would be in ng/ml. I am doing a research paper in human genetics on IGF and this would be a good opportunity to get your feedback.
Thanks,
